This study presents a simplified hand suture microanastomosis technique using a cuff and glue apparatus. The novel method achieves ideal intima-intima union and improves healing, making microvascular surgery more accessible.

Area of Science:

  • Vascular Surgery
  • Microsurgery
  • Biomaterials

Background:

  • Hand suture microanastomosis is technically challenging.
  • Existing methods can be time-consuming and require specialized skills.

Purpose of the Study:

  • To describe a simplified microanastomosis technique.
  • To evaluate the efficacy of a novel cuff and glue apparatus for vascular anastomosis.

Main Methods:

  • Rat vena cava and intestine were used for the study.
  • A simplified microanastomosis was performed using an everted cuff and tissue glue.
  • The technique involved precise intima-intima apposition facilitated by the cuff system.

Main Results:

  • The developed microanastomosis achieved an ideal intima-intima union with a waveform shape.

  • The technique demonstrated improved healing processes.
  • The procedure, after brief training, could be completed within 10 minutes.

    • Conclusions:

    • This simplified microanastomosis technique using a cuff and glue apparatus is effective and efficient.
    • The method avoids foreign body reactions associated with cuffs.
    • It offers a promising approach for simplifying microanastomosis research and advancing tissue glue technology.
